To aZZ whom it may concern.-

Be it known that I, JOHN H. J ONES, a citizen of the United States, residing atFostoria, in the county of Seneca and State-of Ohio, have invented certain new and useful Improvements in Building-Blocks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in building-blocks.

The object of the invention is to provide a block in which is formed longitudinally and transversely disposed passages which when the blocks are built into a wall will coincide,

sage and having grooves or channels formed 7 on its ends which when the blocks are laid in a wall will form other vertical passages.

With these and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a perspective view of a portion of the corner block. Fig. 2 is a perspective view of one of the corner-blocks. Fig. 3 is a horizontal sectional view thereof. tional view of the same. Fig. 5 is a perspective View of one of the side-wall blocks, and Fig. 6 is a vertical sectional View of the same.

Referring more particularly to the drawings, 1 denotes a block which may be formed of any suitable material in a mold constructed for the purpose. I

In Figs. 2, 3, and 4 is shown the form-of block used at the corners of the walls of the building, said block consisting of a right-angularly-shaped body portion 2, in which is formed a horizontal longitudinally-disposed right-angularly-formed passage 3, extending entirely through the block, as shown. In the Fig. 4: is a vertical seccorner of-.the body portion 20f the block is formed a vertically-disposed passage 4, which extends through the'bloc'k and intersects the passage 2. In one or both ends of the block are formed vertically-disposed grooves or channels 5, which when two blocks are brought together form a passage between the same.

In Figs. 5 and'6 of the drawings is shown the form of blockused in constructing the side walls of the building, said block being rectangular and oblong in shape, and in the same is formed a horizontal longitudinallydisposed passage 6. This passage 6 extends entirely through said block, and when the sameis laid up in a wall said passages coincidei and form a passage entirely through the wal a i Midway between the, ends of the block is formed a vertically-disposed passage 7 which extends entirely through the block and intersects the longitudinal passage 6.- In each end of the block are formed vertically-disposed grooves or channels 8, which when said blocks are arranged in position will form passages between the same which will correspond to the passages 7 formed in the centers of the block.

A wall constructed of blocks formed as herein shown and described will be thoroughly Various changes in the form, proportion,

and the minor details of construction may be resorted to without departing from the principle or sacrificing any-of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

A building-block ofsubstantially rectangular cross-section, a longitudin ally-disposed rec tangular air-passage extending through the In testimony whereof I have hereunto set center of said block, and avertically-disposed my hand in presence of two subscribing \vit- IO rectangular passage extending entirely nesses. through the block and intersecting said lon- 5 gitudinally-disposed passage, the Walls of said passages being of substantially uniform thiek- Witnesses: ness to insure equal expansion and contrae- LUTHER ANDERSON, tion of the block, substantially as described.
